Specification of Letters Patent.

Patented May 20, 1919.

Application filed February 25,1918 Serial No. 219,005.

To all whom it mayconcern:

Be it known that I, CHARLES HAINES WILLIAMS, a citizen of the UnitedStates, residing at the city of Chicago, county of Cook, and State ofIllinois, have invented a certain new and useful Improvement 1nFourth-Point Supports for Brake-Beams,of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertaihs to make and use the same, reference being hadto the accompanying drawings, forming part of this specification.

"Figure l is a conventional. plan view of a brake beam showing myimproved fourth point support.

Fig. 2 is a vertical sectional" view through one of the supports.

Fig. 3 is a side elevational view of the form of support shown in Fig.2. Fig. 4 is a detail view of a modification.

I Fig. 5 is a cross sectional View of the modification shown in Fi 6.

Fig. 6 is a side elevational View of the modification shown in Fig. 5.

Figs. 7 and 8 are end and side elevational views of anothermodification.

Fig. 9 is a cross sectional view of another modification.

Figs. 10 and 11 are end and side elevational views of anothermodification.

- This invention relates to new and useful improvements in fourth pointsupports for brake beams, the object being to obviate the necessity forthe use of right and left hand castings and to enable the use ofmalleable, wrought iron, steel, pressed or rolled parts, whereby theproper support or chair may be providedforsecuring in position thesupport. These fourth point supports are frequently applied to the brakebeams after the beams are assembled and it has been found to bepractically impossible to use gray iron castings which have been formedwith their wings suiiiciently opened to slip over the tension rod aswhen said wings are closed they are liable to break,

It is therefore proposed that the sliding portion of the chair be madeof the casting which is fastened or secured to the tension rod, trussrod, or other fixed part of the fourth point supports in which 1indicates the compression member, 2 the tension memher, 3 the strut, 4the brake heads, 5 the tracks for the fourth point supports, and 7 thespringplank or part of the truck to which the tracks for the fourthpoint supports are connected.

8 indicates the bracket embracing the tension rod whichbracket is formedwith an opening in its lower portion which opening receives a teat 9 thecasting or stirrup 9 forming a rubbing or wearing surface. This castingis provided with a saddle for receiving the tension rod which saddlecarries the tiat 9 and under the saddle is the wearing s oe.

In Fig. 4, I have shown a similar construction in which the stirrup 9 isin the form of a semi-sphere.

In Figs. 5, 6, 7, and 8, I have shown modified forms in which the parts10, 11, 13 and 14 are hinged together. In Figs.'5 and 6, a pintle 15 isemployed while in Figs. 7 and 8 a detachable hinge connection is shown.

In Fig. 9, 19 indicates a clamp embracing the tension member andconfining the wearing shoe 20 in position.

In Figs. 10 and 11, there is a malleable casting 21 clamped on thetension rod for holding a roller '22 inplace.

It will be readily understood, of course, that still othermodifications'and adaptations of my improved fourth point support forbrake beams may be made without departing from the spirit and scope ofwhat I claim to be my invention.

What I claim is: I

1. The combination with a supporting part of a brake beam, of a clampingmember, and a separable supporting member supported in position by saidclamping member and held against vertical and lateral movement thereby.

2. The combination with a supporting part of a brake beam, of a clampingmemeoeiee ber composed of nonit'rengible material, and capable ofattachment to either the left or 10 a separable supporting membersupported in righthend side of the beam, position by said nonfrengiblepert and held In testimony whereof I- hereunto eafix my egeinbstvertical and, lateral movement signature this 9th day of February, 1918.flier-e17.
